### MLB-161 APC rack could not be lowered

APC rack could not be lowered.

As a result, a command was executed, which required the APC rack to be lowered, and it could not be lowered.

What you should do:

1. Check the command's definition and correct the measurement routine.

2. Correct the problem with the APC racks lower/raise capability.

3. If the error reoccurs, contact your Giddings & Lewis service representative.
